Sleep regressions are common in 6-month-old infants and can be caused by various factors. At this age, babies are reaching important developmental milestones, which can be disruptive to their sleep. They are also more aware of their surroundings and sensitive to sleep disturbances, often practising new skills like sitting up and crawling. Sleep regressions can also be caused by changes in routine, such as travel or missing naps, as well as teething, illness, and discomfort. Separation anxiety can also play a role, with some babies becoming clingier and experiencing stranger anxiety. While sleep regressions are normal, there are strategies to help improve your baby's sleep, such as maintaining healthy sleep habits and creating a calm and distraction-free sleep environment.

Sleep regression
It is common for 6-month-old babies to experience sleep regression. While it is not permanent, it can be challenging for caregivers.
Signs of Sleep Regression
There are several signs that your 6-month-old is experiencing sleep regression. These include:
- Increased night waking: Around 25-50% of babies continue to wake overnight at 6 months.
- Trouble falling asleep: Your baby may start resisting sleep during the day or at bedtime.
- Waking up very early: It is not uncommon for infants to wake up earlier than usual during a period of poor sleep.
- Short or skipped naps: Your baby may have trouble falling asleep and staying asleep during the day.
- Crying out in their sleep: This could be due to overtiredness, hunger, discomfort, or moving from one sleep cycle to the next.
Causes of Sleep Regression
There are several factors that may cause sleep regression in 6-month-olds. These include:
- Developmental changes: Your baby may be learning new skills such as rolling, sitting, or babbling, which can interfere with sleep.
- Separation anxiety: Your baby may become clingier and may cry when you walk away from their crib.
- Teething: The discomfort and pain associated with teething can make it difficult for your baby to fall asleep or sleep through the night.
- Changes in sleep needs: Your baby's maturing circadian rhythm (internal clock) may become more influential but may not align with their homeostatic sleep pressure (the buildup of sleep need).
- Sleep-onset associations: If your baby relies on being rocked, fed, or held to fall asleep, they may wake up more frequently and have shorter naps.
Tips for Managing Sleep Regression
- Maintain healthy sleep habits: Try to keep a consistent bedtime routine and ensure your baby gets enough sleep during the day.
- Establish sleep cues: Use sleep cues to calm your baby before putting them down in their crib.
- Address the underlying cause: If teething is the issue, provide your baby with soothing options like teething toys or cool purees to ease the discomfort. If it's related to developmental growth, ensure they have time to practice their new skills during the day.
- Get fresh air: Taking your baby outside during the day can help regulate their circadian rhythm and improve their sleep.
- Consult a pediatrician: While sleep regression in 6-month-olds usually doesn't require medical attention, you can discuss your baby's sleep during check-ins with their doctor.

Separation anxiety
The development of object permanence, which typically occurs around 6-8 months, can also trigger separation anxiety. At this stage, babies understand that when something goes out of sight, it still exists. They realize that when a caregiver leaves the room, the caregiver is doing something else, somewhere else. This can cause them to cry out for the caregiver or want them to come back.
To help manage separation anxiety and improve sleep, it is important to maintain a consistent sleep schedule and bedtime routine. Providing extra cuddles, kisses, and reassurance during the day can also help, as can offering comfort through patting and soothing if the baby wakes up during the night. Introducing a comfort object or "lovey" can provide a sense of security, but it is recommended to wait until the baby is 12 months or older to introduce such an object at nap and bedtime.

Developmental milestones
It is common for 6-month-olds to experience sleep problems. This phenomenon is known as "6-month sleep regression". During this period, babies may experience an increased number of awakenings at night, trouble falling asleep, and early morning wakings. These sleep issues are often temporary and related to their developmental progress.
- Motor Skills: By 6 months, babies are gaining more control over their bodies and are becoming more mobile. They may be able to roll over in both directions (front to back and back to front), sit up with support, and may even start to prepare for crawling by rocking back and forth on their hands and knees.
- Sensory and Cognitive Development: At this age, babies are exploring the world through their senses and are becoming more interactive. They enjoy playing games like peek-a-boo and will respond to their name. They may start to babble and make different sounds, imitating the tones and expressions they hear from caregivers. They also start to understand object permanence, realizing that objects continue to exist even when they are out of sight.
- Social and Emotional Development: Six-month-olds are becoming more social and expressive. They smile, laugh, and respond to the emotions of others. They may start to show signs of separation anxiety, becoming clingy or upset when a caregiver leaves their sight. This is a normal part of their emotional development.
- Communication: Babies at this age are highly responsive to voices and tones. They recognize familiar faces and voices and respond to their names. They start to understand simple words and instructions. They also begin to communicate their needs through gestures, sounds, and facial expressions.
Remember, every baby develops at their own pace, and it's important to discuss any concerns with your child's doctor. The CDC's Milestone Tracker app can be a helpful tool to monitor your child's development and identify any potential areas of concern.

Sleep training
It is common for 6-month-olds to experience sleep regression, which can manifest as increased night waking, trouble falling asleep, early morning waking, and short or skipped naps. Sleep regression at this age is often associated with developmental strides and changing sleep needs. For instance, your baby might be learning to roll over, sit up, or babble, and this interferes with their sleep. Separation anxiety, which can develop around 6 months, may also cause your baby to cry when you walk away from their crib.
Establish a bedtime routine
A consistent bedtime routine acts as a signal to your baby that it's time to wind down and prepare for sleep. This can include activities such as a warm bath, reading a book, or singing lullabies. By following the same routine each night, your baby will learn to associate these activities with sleep, making it easier for them to relax and drift off.
Create a sleep-conducive environment
Make sure your baby's bedroom is optimised for sleep. This includes using blackout curtains to block out light, lowering the temperature to a comfortable level, and using white noise to block out external noises. A dark, cool, and quiet room can promote better sleep for your baby.
Address separation anxiety
If your baby cries when you leave their crib, try gently comforting them without taking them out of the crib. You can rub their head or speak in a calm, soothing voice until they relax. Gradually move away from the crib once they have calmed down and are ready to fall asleep.
Focus on self-soothing
Be consistent
Consistency is key when it comes to sleep training. Stick to the same bedtime routine, sleep schedule, and techniques to reinforce positive sleep habits. Avoid making exceptions, as this can confuse your baby and set back the progress you've made. Remember, sleep training takes time and patience, so don't give up too quickly.
Remember, it is always recommended to consult your paediatrician or a healthcare professional before starting any sleep training program to ensure it is suitable for your baby's needs.

Teething
To soothe a teething baby at night, you can try offering a cooling gum massage with a clean finger or a durable teething ring. Teething toys made of solid plastic can be stored in the fridge or freezer to provide extra relief. Cold washcloths or frozen bananas (for older babies who are eating solids) can also be chewed on safely.
It is recommended to stick to your baby's normal bedtime routine as much as possible to avoid prolonging sleep disruptions. You can offer extra comfort and snuggles before sleep, but try to avoid introducing new sleep associations that may be hard to break later, such as rocking your baby to sleep. If your baby is struggling to sleep due to teething pain, you can consult your paediatrician about safe pain relief options, such as baby acetaminophen or ibuprofen.
While teething can cause sleep disruptions, it is important to be mindful of other potential causes of sleep problems in 6-month-old babies. Growth spurts, illness, travel, developmental milestones, and changes in sleep architecture can also contribute to sleep regressions.

Frequently asked questions
Yes, it is common for 6-month-old infants to experience sleep regression, which can manifest as increased night waking, trouble falling asleep, early morning waking, and short or skipped naps. This is often due to changes in sleep cycles, developmental milestones, teething, illness, or changes in routine.
Sleep regression in 6-month-olds can be attributed to various factors, including developmental milestones such as sitting up, crawling, or babbling; changes in sleep cycles; teething; illness or discomfort; and changes in routine, such as travel or missing naps.
The duration of sleep regression can vary, but it typically lasts for a short period, especially if caregivers implement healthy sleep habits. Sleep problems often resolve within a few days or weeks, but a plateau in sleep improvements may continue for longer.
To help your baby through sleep regression, maintain a consistent sleep routine and a familiar environment. Ensure their room is dark, quiet, and distraction-free, and consider using room-darkening shades and a noise machine. You can also try sleep training methods such as cry it out, fading, gentle, or the Ferber method. Additionally, wean your baby off nighttime feedings gradually over about two weeks.
Sleep problems in 6-month-olds usually do not require medical attention. However, if you are concerned or notice other issues, consult your paediatrician during regular check-ins. Prioritize self-care and ensure you are getting adequate rest, as healthier caregivers are better equipped to provide loving and attentive care for their infants.
